BA.2.86 is a subvariant of the Omicron variant of SARS-CoV-2, the virus that causes COVID-19. It was first identified in India in early 2023 and has since spread to other parts of the world, including the United States.

BA.2.86 is more transmissible than other circulating Omicron variants, meaning that it is more easily spread from person to person. However, there is no evidence that it causes more severe illness than other Omicron variants.

BA.2.86 is becoming increasingly prevalent in the United States. It is now the third most common variant in the country, behind HV.1 and EG.5.

The CDC is monitoring the situation and is advising people to stay up-to-date on their COVID-19 vaccinations and boosters to protect themselves from BA.2.86 and other variants.

Here are some additional details about BA.2.86:

• It has several mutations that make it more transmissible than other Omicron variants.

• It is able to evade some of the immune protection that people get from vaccines and past infections.

• It is not yet clear whether BA.2.86 will cause a surge in COVID-19 cases in the United States.

Overall, BA.2.86 is a variant of concern, but it is important to remember that vaccines and boosters are still very effective at protecting people from severe illness, hospitalization, and death from COVID-19.

I will continue to monitor the situation and provide updates as needed.

In the meantime, please stay up-to-date on your COVID-19 vaccinations and boosters, wear a mask in indoor public places, and wash your hands frequently.
